Great heat mat for cold weather

Great heat mat for cold weather
AC Infinity has basically cornered the market in the growing market. The heat mat is large enough for my 3x3 tent floor and two 3 gallon pots on top. UL rated mat water proof and controller has an awesome range for settings. Cold floor is a thing of the past with its even heat distribution. The customer service is a pleasure to talk too and warranty is always honored. This company is really changing the outlook for growers with the high-tech products that are being produced. Slowly switching everything over to AC Infinity.
